Watch out, O.J. SimpsonCaitlyn Jenner is coming for you! Although it’s been literal decades since her ex-wife Kris Jenner was accused of having an affair with the disgraced football star, Cait is determined to finally find out what really went down between the two.

An insider told Radar Online, “Caitlyn wants to know the truth about what really happened between him and Kris and if it’s true they had an affair.” They added, “She’s confident Kris hasn’t told her the truth and she wants answers. If Kris is going to stand there and call her a liar, she’s going to prove who the biggest liar of all is.”

We’ll be interested to see how this all plays out — and if Caitlyn will actually follow through. Because TBH, it’s probably not the best idea to mess with a dude who was convicted of armed robbery and was also accused of murder…
